Enter the pulse width and the period into the calculator to determine the duty cycle.
Duty Cycle Formula
The following formula is used to calculate a duty cycle.
D = PW / T
- Where D is the duty cycle
- PW is the pulse width (s)
- T is the period (s)
Duty Cycle Definition
A duty cycle is defined as the ratio of the pulse width to the period of a transmitter and is a measure of the time that the transmitter is emitting a signal.
Duty Cycle Example
How to calculate duty cycle?
- First, determine the pulse width.
For this example, we will say the pulse width is .03 seconds.
- Next, determine the period.
For this example, we will assume the period is .05 seconds.
- Finally, calculate the duty cycle.
Using the formula above we find the duty cycle is: .03/.05 = .60 = 60%.
A duty cycle measure the amount of time a transmitter is emitting a signal. This time is often a fraction of a total frequency period. The longer the duty cycle, the stronger the transmittion.
